In an effort to block the use of modified chips in its Wii game console, Nintendo is expected to make changes to the circuit layout.

Citing retail channels in Taiwan, Digitimes.com reports that the new Wiis, which are part of new shipments of the console, have an altered circuit layout that makes modification more difficult than in earlier versions.

Providers of Wii modification services in Taiwan think Nintendo could adopt BGA (ball grid array) IC packaging to prolong the time needed by hackers to develop new modchips to at least four months. The longer waiting time would likely reduce the willingness of some users to modify the consoles.
